Amy is a wonderful sub. That doesn't mean she isn't going to be punished, it just means she is going to have a huge smile on her face while it is happening. It is hard to tell from her expression whether she feels the difference between when O.T. is whipping her ass and when he is fucking her senseless with the pogo. The only thing that clues us in is when the sounds she makes change from moans to whimpers and back again.
